arms,of which the following is a specificand especially the barrels, of bolt-operated firearms. l a i a An attempt to clean the boreofthebarrel from the muzzle tend is very'likely to seriously harm said interior, andespecially the rifling while before myl invention anyattempt to'clean from the chamber endof the barrel in bolt-operated firearms has been cleaning-material can not beheld so as to a be properly engaged'vby the cleaning rod with the result that the swab slips out of po-' 1 sition and is not carried into the barrel by the cleaning-rod except peatedand painstakingefforts.

p fssibly after fre- My invention is a device for overcomin these ob ect10ns and conslsts m a member "which guides the swab to the boreof they barrel and which has an entrance readily accessiblefor insertion of the swab and cleaning rod in proper relative position. i A feature of said member is its construci tion adapting it for use withstandard types out below. a t a l V l In the drawings :fgFigurel is a longitudt V 40 i firearm of the boltoperated type, the fireof bolt-operated rifles and another feature I p p guide rod is of substantially the same d ameter as the bore of the barrel but it might be is the means for holdingit in place while in Other inventional features will bepointed nal section illustrating myattachment in a arm being broken away and partly illustrated in dotted lines; Fig. 2 is a plan of the structure of Fig. 1 with the exception of the portion in dotted lines; and Fig. 3 illustrates the attachment by itself. a

a v I have illustrated myfattachmentin use in abolt-operated Springfield rifle although, of

course, it may be used with many other types firearm. Barrel A has bore a, cartridge chamber a, ramp a andrec'eiver housing a which servesas an inner bearing for-the ordinary "bolt. VB is the outer bearing for said bolt and has'theordinary interior cy;
